Display apparatus

Provided is a display apparatus, including a substrate including: a pixel electrode; an organic insulating film; a common electrode laminated on the organic insulating film so as to be opposed to the pixel electrode via an insulating layer; a common signal line connected to the common electrode; and a transistor configured to apply, to the pixel electrode, a voltage signal input to a signal line. The pixel electrode is connected to a source electrode of the transistor via a through hole formed through the organic insulating film. The through hole includes, in at least one extending portion formed by retreating the organic insulating film toward an outer side of the through hole, a stepped portion formed by laminating a part of the common signal line.
